A sexually transmitted disease (STD), a.k.a. Venereal disease (VD), is an illness that has a significant probability of transmission between people by means of sexual contact, including vaginal intercourse, oral sex, and anal sex. Increasingly, the term sexually transmitted infection (STI) is used, as it has a broader range of meaning; a person may be infected, and may potentially infect others, without showing signs of disease. Some STIs can also be transmitted via the needles used in IV drug use, as well as through childbirth or breastfeeding. Sexually transmitted infections have been well known for hundreds of years.
Some STD's show no symptoms at all. It is advisable to get screened after unprotected sex. However depending on which STD you have contracted these may be among them:
Chlamydia, Gonorrhoea, and syphilis are caused by bacteria, while AIDS, genital herpes, genital warts, and hepatitis B are caused by a virus. The pathogens that cause STDs are found in bodily secretions such as semen, blood, vaginal fluids, and sometimes saliva. Most of the organisms are spread by either sexual or personal contact.
If you are in a risky group always have regular tests.
Never attempt to treat an STD yourself. These diseases are contagious and dangerous. You must see a doctor.
Bacterial STDs can be cured with antibiotics if treatment begins early enough. Viral STDs cannot be cured, but you can manage symptoms with medications. There is a vaccine to prevent hepatitis B, but it will not help if you have already contracted the disease.
